Description

{APPARATUS FOR CHARGING MATERIAL}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a conveying-loading apparatus, and more particularly, to a conveying-loading apparatus for distributing a raw material in a loading hopper of a sintering machine.

Generally, the sintering method is a sintering method in which sintered raw materials such as minute iron ores and subsidiary materials discharged from a light-emitting hopper and mixed through a dream mixer are charged into a sintering truck at a predetermined height through a charging hopper and a drum feeder, After the surface of the raw material is ignited, air is forcedly sucked downward to sinter the sintered raw material of the sintered bogie to produce sintered ores.

In the sintering machine, the feedstock is fed through the shuttle conveyor to the loading hopper, and then the raw material is fed to the sintering truck from the loading hopper. At this time, the air permeability in the raw material charged into the sintering vehicle has a great influence on the sintering recovery rate. Therefore, various methods for inducing segregation charging have been researched when the sintering raw material is charged into the charging hopper.

The raw material distribution surfaces 32 and 42 are disposed on the raw material distribution surfaces 31 and 32, 41 to fall to the side walls 12, 13 of the containing chamber 11.

The width W1 of the raw material distribution surfaces 31 and 41 can be formed to be relatively narrower than the width W2 of the raw material dropping surfaces 32 and 42. [ The width W1 of the raw material distribution surfaces 31 and 41 can be about half the width of the raw material conveyance belt 6 and the width W2 of the raw material fall- And the width of the protruding portion may correspond to the width of the protruding portion.

The raw material falling down from the raw material dropping section 7 of the raw material conveying belt 6 is divided equally by the raw material distribution surfaces 31 and 41 and then discharged along the raw material dropping surfaces 32 and 42 And is supplied to both side walls 12 and 13. The intersection 25 of the first dropping guide plate 30 and the second dropping guide plate 40 can be positioned right below the material dropping portion 7 of the raw material conveying belt 6. [

The angle regulating device 50 is not limited as long as it can rotate and drive the first falling guide plate 30 and the second fall guide plate 40 in an overlapping or unfolded manner.

Vibration generators (35, 45) for generating vibration may be provided on the back surfaces of the first drop guide plate (30) and the second fall guide plate (40).

The vibration generators 35 and 45 generate vibrations in the first fall-inducing plate 30 and the second fall-inducing plate 40, thereby preventing the generation of adhering light in the fall-down regions 32 and 42, And performs the function of inducing the flow of the raw material.

Hereinafter, the operation of the transporting apparatus according to the embodiment of the present invention will be described with reference to FIG.

The raw material conveyed to the raw material conveying belt 6 falls from the raw material dropping section 7 and strikes against the transporting and loading device 20.

The raw materials which are distributed to the both sides by the raw material distribution surfaces 31 and 41 and move along the raw material distribution surfaces 31 and 41 respectively are separated by the dispersion ribs 33 and 43 in the width direction of the raw materials 32 and 42 And then falls to the side walls 12 and 13 of the housing chamber 11. [

At this time, the angle adjusting device 50 appropriately adjusts the angle between the first fall-inducing plate 30 and the second fall-inducing plate 40 according to the level of the material to be charged into the storage chamber 11.

As a result, raw materials are accumulated on both side walls 12 and 13 of the storage chamber 11 to form a V-shaped charging shape, so that the opposing particles are moved toward the center by gravity and accumulated, On both side walls 12 and 13 side.

Since the raw materials constituting the charging shape are supplied to the sintering bogie as they are, the atomized raw materials can be uniformly distributed on both sidewalls of the sintering bogie, thereby suppressing the ventilation of the side walls of the sintering bogie during sintering and reducing air loss The generation of unburned ore is suppressed and the recovery rate and productivity of the sintered ores are improved.
